Sorry about missing video. That update was for "version 1" of the Set Target System, so I removed it when I updated it to "version 2" since it's different in how it's used. Version 2 is for dual- and triple-boxers and as a result uses two to three keys in total, whereas "version 1" only used one key. Original version also didn't support instant Lead switching, which the new version does.
Unfortunately I haven't made a video for Version 2 as of yet.
